JOHN B. BATT, OF \VILLIAMSVILLE, NEW YORK.

CAR=SIGNAL- SPECIFICATION forming part of Letters Patent No. 269,621, dated December 26, 1882,

To' all. whom it may concern Be it known that I, JOHN B. BATT, of Williamsville, in the county ot' Eric and State of New York, have invented a newand useful Improvementin Railway-Signals, of which the following is a specification.

This invention relates to that class of railway-signals which are'designed to give notice of a locomotive or train approaching a streetcrossing or other place where the track is liable to be obstructed, and which are audible for a suitablelength of time before the locomotive or train reaches such crossing or place, and which consist of a stop located near the track at the proper distance from the streetcrossing or other place in the direction from which the 4trains approach the same, and of mechanism which is operated bythe stop on the track, as the locomotive passes over the stop, in such manner that the whistle is thereby sounded automatically.

My invention consists of the -particular construction of the mechanism whereby the whistle is automatically sounded, as willbe hereinafter fully Aset forth.

In the accompanying drawings, Figure l is a fragmentary elevation of a locomotive provided with my improvement. Fig. 2 is a vertical section, showing the mechanism in the position in which the whistle is sounded. Fig. 3 is a front elevation, on an enlarged scale, of the mechanism wherehythe whistle is operated. Fig. 4 is aside elevation of the stop secured to one of the rails.

` Like letters of reference refer to like parts in the several figures.

A represents the rails of the track, and B represents a stopsecured to the outer side of the rails and projecting slightly above the tread of the rails, but not high enough to come in contact with any ofthe ordinary parts of th'gplocomotive orcars running on the track.

C represents a steam-whistle, which may be arranged in front of the smoke-stack, as shown in the drawings, or in any other convenient place upon the locomotive.

c represents an arm secured to thc plug of the whistle O for the purpose of turning` the plug, and d represents a rod which extends from the end ofthe arm c downwardly and connects with a weighted lever, D, underneath the front platform, E, of the locomotive. The

lever D is pivoted at its front end, by means of a bracket, c. or other suitable means, to the under side of the platform E.

frepresents an arm which engages against the under side of the lever D, and which supports the latter in a position in which itcloses the whistle O by means of the connecting-rod d. The armfis mounted on a rock-shaft, g, which turns in bearings z, secured tothe under side of the front platform of the locolnotive.

t' is an arm secured in adepending position to the outer end of the shaft g, so that the lower end will come in contact with the stop B on the track as the engine passes over the same.

j represents a rod which is attached to the arm z', and which extends from the latter to the cab of the locomotive, where it terminates in a handle, It', in convenient reach of the engineer or fireman.

The stop B is secured to the track at such a distance from the street-crossing or other point where the train is required to signal its approach that ample warning is given of the approach of the train. If therailwayhas but. a single track, over which trains movein both directions, a stop B is secured to the track on both sides'of the street-crossing, at proper distances from the same, and in either clase on that side of the track where the stop willcome A in contact with the depending arm of the alarm mechanism on the locomotive. As the arm t' strikes the stop B t-he arm is turned backwardly, whereby the arm f, which' is mounted on the same shaft, g, with the arm t', isswung forwardly and away from under the weighted lever D, as shown in Fig. 2. The lever D now descends by gravity and draws the rod d downwardly, whereby the steamcock attached to the whistle C is opened and ,the latter is sounded. fhe parts remain in this position, with the whistle blowing, until a sufficient signal has been given, when the attendant in the cab of the locoinotivepushes the rodj forwardly, whereby the supportingarmfis swung back underthe lever D, thereby raising the latter and shutting the steamcock of the whistle by the rod d. The lever D is preferably provided on its under side witha notch or depression, in which the end of the supportingarm f engages to more securely IOC support the lever on the arm. The latter is preferably provided with a weight, I,to retain the same in an inclined position when disengaged from thelever I).V

Suitable stops,1n m,may be provided on the frame or some other suitable part of the locomotive, whereby the movement of the mechanism is limited.

By my invention the signal is given automatically at the proper place, and the engineer and fireman are thereby relieved from the duty of observing the signal-posts and other de vices now used on railroads for calling the attention of the engineers to the fact that they are required to give a signal in passing suoli place. These signals are now frequently omitied or given too late, because the engineer did not notice the signal-post in time, when the i'ailnre to give the signal at the proper place may cause an accident.

I claim as my invention- 1. The combination with'alocomotivewhisl ile, ot' a weighted lever, l), a rod, d, connecting said lever with the whistle, a horizontal shaft, g, provided with an arm,f, supporting said lever, anda depending,r arm, i, attached to said shaft and adapted to come in contact with a stop on the t-rack, whereby the armfis Withdrawn from the weighted lever and the latter caused to descend, thereby sounding the whistle, substantially as set forth.

2. The combination,with alocomotive-whistle, of a weighted lever, D, a rod, d, connecting said lever with the whistle, a horizontal shaft, g, provided with an arm,f, supporting said lever, a depending' arm, i, attached to said shaft and adapted to be operated by a stop on the track, and arod,j, extendingfrom one ot' the arms secured tothe shaft gto within reach ot' the attendant, whereby the shaft and arms can be readily returned to their former position after the alarm has been sounded, substantially as set forth.
